Mopars are famous for the main wire to be shorted out. check the fire wall black electrical connection box under the hood where all the wires go through to under the dash by the drivers side . sometimes they get old and just break too. the main wire has a fusible link on it, check that too. it is usually something simple.

 

Hey,

Did you ever get this problem resolved?

Hope your up and running and this one is behind you.

Happy Motoring.
